Didn't fix anything, and for some reason it gave cxm0 and cxm1 irq's 17 and 18 now... one more than what they were. > 2. Try to use as less hardware as possible. I striped out everything but the harddrive, video card, nic card and tv tuner. Still resulted in same irq's and rebooting. > 3. Try LINUX for TV recording (although I saw LINUX crashing with my TV card, > too)... :-) Actually, I currently have a Gentoo computer hooked up to my TV which had the PVR500 in it. That computer doesnt have the best specs, and it was too slow to watch a recording while it was recording something else. So I'm attempting to put this card in my FreeBSD box. The Gentoo computer worked great if I didnt watch a recording and record something at the same time. Never crashed on me once for the few months I was using the PVR500. Another little tidbit: it seems that if I do a cat /dev/cxm0 > /dev/null, it will go alot longer without rebooting. Thanks for your tips... Any other ideas?? Sean
